To all whom it may concern:

Be it known that I, VICTOR A. Benson, a citizen of the UnitedStates, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Adjustable DoonI-Ianger, of whichthe following is a specification.

This invention relates to adjustable door hangers, and, while designed especially for elevator doors, is of great advantage when used on other kinds of sliding doors.

The main object of the invention is to-positively keep the wheels in absolute alinement withthe door, andto provide a device which, in its application to the door, does not reuire adjustments to aline the wheels with t 1e door, the alinement being-alwayssecured upon attaching the deviceto the door.

Another object is to provide a device of the characterdescribed which may readily be adjusted so that the door Will -ban in a perfect vertical position at right ang es to the track, or may be adjusted so that the stile of the door will lie parallel with the easing or jamb of the door way should the latter be out of plumb.

Another object is to provide a device of the character described which may be constructed cheaper than a set of door hangers of ordinary construction and which may be applied to the door with greater facility and in much less time and with less fitting than required for ordinary door hangers.

The accompanying drawings illustrate the invention, and referring thereto :Figure 1 is a front elevation of an elevator door equipped with the invention. Fig. 2 is an enlarged section on line w x Fig. 1. Fig. 3 is a section on line r w Fig. 2. Fig. 4 1s a perspective in detail of the connection bolt. Fig. 5 is a front elevation of a modified form of hanger, showing only the up er ortion of the door to which it is attached ig. 6 is a front elevation of another form, showing only the upper portion of the door to which the hanger is attached.

In the preferred form, 1 designates the door having a top frame bar 2.

3 is a hanger bar, formed preferabl of a single piece of metal, which extends su stantially the full width of the door and has downturned ends 4. Journaled near each end of the hanger bar 3 are wheels 5 with grooved peripheries which travel on the track 6.

It will be noted that the wheels 5 are both journaled t0 the "bar3, and as this is a "rigid member from end to end the two wheels properly j ournaled therein are fixed-in alinement with respect to the bar 3 .and cannot In its preferred form, each connection bolt comprises a threaded stud 7, formed at its upper end witha flattened-wing 8, the latter having a laterally projecting stud 9, and

immediately below the stud 9 the wing 8 is provided witha perforation 10. The wing 8 ies flatly against the downturnedend 4 of the hanger bar 3 and its'stud 9 is received in :a hole formed in the end 4. A screw 11 asses through the orifice 10 and is screwed into the 1 end A and "this construction rigidly attaches the connection bolt to th'eend A.

The stud 9, as will be noted, is made ciently heavy to carry the Weightofthedoor 1, ',the screw 11 being reli'evedof the weight and servin mainly to detachably secure the wing 8 to t e member 4. Riveted to the top bar 2 of the door are two bracket plates 12, each being arranged underneath the associated connection bolt, and each bracket plate 12 is provided with a screw threaded opening to receive the threaded stud 7 of the connection bolt, the latter being screwed into the bracket plate 12 before lts wing 8 is attached to the member 4. The wing 8 when detached from member 4 permits the connection bolt to be turned in the bracket 12 to adjust the elevation of the wing 8 with respect to the top bar 2, and after the proper vertical adjustment has been made the wing 8 is secured to the member 4. This construction permits either side of the door to be adjusted vertically with respect to the hanger bar 3 to bring the door plumb or into parallelism with the door-way.

The guard plate 13 is formed with a corner nut 14 which is screwed on the stud 7 and has a lateral lug 15 to receive a screw 16, the latter being screwed into the bracket plate 12. When in position, the guard late 13 projects under the lower edge of t e track rail 6, as clearly shown in Fig. 2, and lies close to the under edge, its purpose being to prevent the door from jumping up sufficiently to permit the wheels 5 to ride off from the track. It is obvious that the guard plate 13 may be screwed up or down on the stud 7 to adjust it to the desired position under the track rail 6, the screw'16 serving to hold the guard late 13 from turning on the stud 7 after it as been adjusted to the desired position.

The modified structure in Fig. 5 is similar in every way to the construction previously described, except that the hanger bar 3 is formed of two sections 3 and 3 which are united by a central bar 17, the latter being riveted to the members 3 and 3 The object of this construction is to enable the hanger to be constructed in large quantities without regard to specified dimensions of different widths of doors. In applying the hanger thus constructed, it is quickly fitted to the proper Width of door by cutting the central bar 17 of the requisite length, after 3 which the members 5 and 3 are riveted thereto, the structure resulting being virtually the same as the form shown in Fig. 3 with the two wheels both secured to a rigid horizontal member.

In the modified construction shown in Fig. 6, the hanger bar 3 is dis ensed with and the connection bolts are ormed with a long wing 18 to which the wheels 5 are 'ournaled. In this form, even though the anger bar 3 is dispensed with, the advantages of the connection bolt construction are retained.

What I claim is 1. In combination with a door, a hanger therefor comprising a bar extending along the top of the door, wheels journaled in o posite ends of the bar, connection bo ts adjustably securing the door to the ends of said bar, a track rail supporting the wheels, and a uard plate screwed on each connection bo t and extending under the track rail.

2. In a door hanger, a wheel, a member in which the wheel is journaled and having an orifice, a connection bolt comprising a threaded stud formed with a fiat wing, a stud on the wing projecting into said orifice and a screw passing through the wing into said member, and means on the door in which said threaded stud is screwed.

3. In a door hanger, a wheel adapted to travel on the track rail, means in which the wheel is journaled, a threaded stud on said means, a guard plate screwed on said stud and extending under the track rail, said guard plate having a lateral lug, means on the door in which said stud is screwed, and a clamping screw through said lateral lug into the last means.

In testimony whereof, I have hereunto set my hand at Los Angeles, California, this 6th day of January 1908.

VICTOR A. BENSON.
